How does one maintain the binary Sn 3.5Ag or Sn 0.7Cu at those precise
eutectic compositions?  And I note that the pasty zones are very large when
compositions deviate. What happens when the ternary SnAgCu alloy in SMT paste
meets and joins the SnCu alloy used in wave soldering?

How do you think the consumers of the world will like the reduced product
lives.  And the product liability suits for failed ICs, turned into sieves
by lead-free melting temps-- can't wait.

Would you fly in an airplane whose black boxes are lead-free or use a
pacemaker....

So how much lead-free is being used today?  Is any one making money from
lead-free?  How many lead-free-ready ovens have BTU or Vitrronics or Cookson
sold?

Lead-free is a bad, expensive joke, and not even Green.
